MONORAIL Filed May 23, 1958 Patented June 27, 1939 UNITED STATES PATENT OFFICE MONORAIL Application May 23,

2 Claims.

My invention relates to the class of devices that are employed for supporting overhead trolleys for the conveyance of loads suspended underneath said trolleys, and an object of my invention, among others, is the production of a device of this'kind that shall be simple in construction and particularly strong and efficient for the purposes for which it is designed.

One form of a monorail embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained is illustrated in the accompanying drawing, in which- Figure 1 is a side View showing one manner of installing a monorail embodying my invention.

Figure 2 is a View on enlarged scale of a broken 01T section of said rail.

Figure 3 is a View of the same in cross section.

Figure 4 is a view in section on a plane denoted by the dotted line 4-4 yof Fig. 2.

In the use of structures of this type it is very essential that a frame comprising the monorail structure shall be extremely rigid and free from liability to sag laterally under load, and my improved structure illustrated and described herein possesses these requisites, such frame comprising an upper bar or chord 5 and a lower rail or chord 6. Both of these chords are of so-called T-shape in cross section, each comprising a plate 'I and a stem or web 8 extending lengthwise along the center of the plate, as commonly found in structures of this kind.

Tie bars 9 are each secured at their opposite ends to the stems or webs of each of the chords and extend in inclined directions relatively to such chords. These tie bars are arranged in sets, the members of each set being located all on one side of the stems or webs of the chords and on the opposite sides of said stems or Webs from the members of another set. They present a zig-zag formation, the opposite ends of each bar terminating substantially at the points of location of ends of tie bars of the opposite set. Preferably a single bolt or rivet I0 is employed to secure the ends of the two tie bars of the opposite sets, or other suitable means may be employed for this purpose.

This arrangement provides a very rigid structure and one particularly free from lateral de-V flection.

This monorail may be suspended in any suitable manner common to structures of this class for the suspended support and conveyance `of loads from one point to another and either within or without buildings, or from one building to another. As illustrating an installation which will particularly show difficulties frequently encountered in the use of structures of this class 1938, Serial N0. 209,469

I have illustrated in the drawing herein my improved monorail arranged to convey loads from trackage within one building across the space between the buildings to trackage within the second building. 'I'he trackage Il Within each of the buildings I2 is suspended as by means of hangers I3 in any suitable manner.

Brackets I4 or any other suitable means may be employed for securing the ends of the monorail section to the sides of the buildings, it being only essential that these means of support shall be sufficient to sustain the loads which may be put upon them. A trolley comprising a pair of wheels l5 and a suspension yoke I6 supporting a hook l1 is located upon the flanges formed by the plates Il of the lower rail, and as shown 1n Figures 2 and 3 of the drawing.

As hereinbefore intimated it will be understood that my invention resides in the monorail structure itself, and in no particular means for supporting it, the means herein shown being one of many which may be employed for this purpose.

In accordance with the provisions of the patent statutes I have described the principles of operation of my invention, together with the device which I now consider to represent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative and that the invention may be carried out by other means and applied to uses other thanthose above set out.

I claim:

l. A monorail comprising two oppositely positioned single T-bars having stems projecting in line toward each other, tie bars arranged in two sets the members of each set being all located on the opposite side of the stems from all the members of the other set, the members of both sets being arranged in zigzag fashion, each end of each of said members of one set meeting the end of a member of the other set on the opposite side of the stem to which said end is secured and means for securing the ends of said bars to said stems.

2. A monorail comprising two oppositely positioned single T-bars having stems projecting in line toward each other, tie bars arranged in two sets, the members of each set being all located on the opposite side of the stems from all the members of the other set, the members of both sets being arranged in zigzag fashion, each end of each of said members of one set meeting the end of a member of the other set on the opposite side of the stem to which said end is secured and a single means for securing adjacent ends of each pair of bars to said stems.
